net: fou: Is FOU/GUE

Hi,

I worked for a company that tried to adop FOU/GUE(which is basically the 
same thing) with some extra features a few years ago.

The project failed unluckily but I am still willing to contribute to 
this protocol if possible.

I've noticed that GUE is now "Expired Internet-Draft" in IETF, but I 
also noticed that fou.c has been rename

to fou_core.c, fou_bpf.c, fou_nl.c.

ref: https://datatracker.ietf.org/doc/draft-ietf-intarea-gue/


I'd like to know:
Should I contribute to this protocol?

Is FOU/GUE dead?

If I'm allowed to get it involved, can I add advanced features(such as 
FEC forward error correction) beyond the draft(version 9)?


Cheers!
